Perpetua: Recyclable monopolymers for protein powder sachet applications

PERPETUA

A more sustainable and at the same time high-barrier laminate solution for pharmaceuticals

A recyclable-ready solution with all the benefits of conventional flexible packaging. PERPETUA is a unique line of full PP high barrier laminates for flexible packaging. PERPETUA is available in a HCR (High Chemical Resistant) version.

This is the first recyclable mono-material solution from Constantia that displays high chemical resistance towards aggressive filling goods. It offers excellent product protection from oxygen, water vapor and light.

Life Cycle Assessment results indicate a reduction of environmental footprint compared to standard multi material solutions. Being HTP-Cyclos certified, its recyclability ranges from 90% to 96%, depending on the individual material specification. With no detrimental aesthetic effects, PERPETUA allows to create an attractive design.

More and more customers want to have a unique brand positioning and brand differentiator and with PERPETUA we can exactly offer that. In addition, it is a more sustainable material that is recyclable. Also, the customized barrier for product safety and long shelf life is a unique selling point.

PERPETUA is a drop-in solution for existing packaging formats based on laminates such as stick packs, strip packs, sachets and compliant with food and pharma regulatory requirements.

Packaging and sustainability

Protecting and preserving valuable goods

Before it is waste, packaging plays an essential role as it protects the valuable content throughout the supply chain and enables a proper and safe delivery to the end-consumer. Flexible packaging is designed to minimize the use of packaging materials, thus it is generally more resource efficient than alternative packaging types. It plays a minor part of a (e.g. food) product’s total environmental footprint, but a major role in preservation.

Hence, insufficient or inadequate packaging would increase the overall footprint tremendously. Flexible packaging with customized barrier protection and appropriate portioning therefore reduces the risk of (food) waste, saving more resources than it consumes.

It is fundamental to ensure that packaging waste is being collected and recycled and does not end up in landfills or the environment.

In this context, it is important that products are harmonized with existing collection, sorting and recycling infrastructure and processes in order to increase the circularity of packaging.

That is why Constantia Flexibles continuously works on the recyclability of its flexible packaging solutions.
